Understanding Orlistat's Mechanism: Your Path to Purchase
How Orlistat Blocks Fat Absorption
Orlistat works through a scientifically proven mechanism that targets lipase enzymes in your digestive system. These enzymes are responsible for breaking down dietary fat so it can be absorbed into your bloodstream. By inhibiting approximately one third of these lipase enzymes, orlistat prevents roughly one third of the fat you eat from being digested and absorbed. This unabsorbed fat passes naturally through your body, reducing the calories you absorb from fatty foods.
This mechanism makes orlistat an effective tool for weight management when used alongside a reduced-calorie, lower-fat diet. The fact that it works locally in your gut, rather than affecting your brain or central nervous system, distinguishes it from stimulant-based weight loss medications.
Orlistat and Vitamin D: What You Need to Know
Because orlistat affects fat absorption, it can impact the absorption of fat-soluble vitamins including vitamin D. This is why healthcare professionals recommend taking a daily multivitamin supplement containing vitamin D while using orlistat. The key is timing - take your vitamin supplement at bedtime, at least 2 hours after your last orlistat dose, to ensure optimal absorption.
At EverydayMeds, we stock orlistat 120mg from £32.99 for 4 weeks (£29.69 with EDM10), Xenical 120mg from £42.99 for 4 weeks (£38.69 with EDM10), and Alli 60mg from £28.99 for 4 weeks (£26.09 with EDM10). All options work through the same fat-blocking mechanism, with 120mg being prescription strength and Alli 60mg offering a lower-strength alternative.
Why This Mechanism Proves Orlistat Works
The beauty of orlistat's mechanism lies in its simplicity and measurability. When you understand that it blocks approximately one third of dietary fat absorption, you can see exactly how it contributes to weight management. Every gram of fat contains 9 calories - so blocking one third of fat absorption directly reduces your calorie intake from fatty foods.
This mechanism also explains why following a lower-fat diet is essential while taking orlistat. Not only does it maximise weight loss potential, but it significantly reduces gastrointestinal side effects. When you eat high-fat meals, the unabsorbed fat has to go somewhere - and that's when you may experience oily stools or other gut-related effects.
